When we first started brushing our children's teeth, we wanted something that would clean their teeth well and prevent cavities, but also that would be safe for them if they accidentally swallowed it. We started using this Aqua fresh training toothpaste, and it has worked well on both sides. Our children have not had any problems with cavities since we started using it for them, and they also have not gotten an upset stomach or any other negative side effects after accidentally swallowing it. Another added bonus is that it seems to have a pleasant and attractive taste. Both of our children got used to it quickly, and they actually wanted to have their teeth brushed so that they could enjoy the taste. This made the jib of brushing their teeth much easier and more enjoyable, and we also knew that we could let them enjoy the taste on their tongue without fear of what would happen to them if they swallowed it.
